Using Autodesk Circuits and a lead-acid battery, you can create a circuit that will act as a variable power supply, outputting a range of voltages from 5V to 20V. After creating the power supply you could drive motors using variable voltage, power microcontrollers, logic circuits, LED strings, analog circuits, and much more.
Once everything is working using the power supply, you can use the battery. I would highly recommend adding a switch in-between your battery and the circuit. It makes it easier to turn the circuit on and off, as well as making it safer. Once you get the circuit working with the battery, you are ready to power your electronic projects!
When powering it on for the first time, use a power supply if you have one. Limit the current to 3A. This will keep everything from blowing up if something was connected wrong. Once everything is working using the power supply, you can use the battery. I would highly recommend adding a switch in-between your battery and the circuit.
Choose only deep cycle batteries. Do not use a car or truck battery, nor a 'marine' battery. If you will be using only one battery, a gel or 'maintenance free' battery will work adequately. For larger systems composed of multiple deep-cycle batteries, select only wet cells or AGM cells.
After creating the power supply you could drive motors using variable voltage, power microcontrollers, logic circuits, LED strings, analog circuits, and much more. This is a good way to learn how basic electronic components can be put together, like a puzzle, to accomplish a task.
